In Fig. l, i is the frame of the machine; 2 two In brackets 18 projecting from the last-named parallel beams journaled therein and each adaptend of the machine are pivoted two pawls or ed to be rotated in each direction; 3 reverse detents 19 which are normally held in the posibrake-straps, whereby when either beam is the tion shown by gravity but adapted to be retracted delivering one the brake therefor is active and the therefrom by the respective tappets, to wit, by 1 other substantially inactive; i an electric motor their buttons 17 having its shaft vertical and provided with abevel At the outset the piece stands Wound on one pinion 5 and whose controller or switch 6 for conof the beams 2; then, before it is passed to and trolling the current thereto, so as to drive the wound up on the other beam with re-rotation of motor in either direction or stop it, is shown in the first beam, the arm 16 corresponding to the og,

Thereafter, in the passing of the piece back and forth between the two beams the tappet corresponding to the delivering beam in each pass will move away from its detent and the other to its detent so as to retract it from its normal position.

Prefacing the description of the means shown by way of example for throwing. the switch or controller 6 it may be generally stated that there is means, as a rod, which is to be moved one way on the passage of the goods in one direction and then reversely on the reverse passage of the goods and which on each movement stores up spring pressure in one or the other of two oppositely active springs so that the spring thus affected willbe effective to throw one Way or the other a shifting structure interposed between them and including such switch, it being understood that one or the other of two detents is holding the shifting structure while the spring power is being thus stored up and that retraction of this detent (as from the beam which is about fully discharged of the goods) effects release of said structure and hence throwing of the switch. The rod or equivalent means, as will appear, may be moved in any way in the proper direction on each pass of the goods, but preferably this is done automatically in the example.

A sliding member or slide comprising tubes 20, guided in the brackets 18, and a casting 21 forms with the motor controller or switch 6, with which it is disconnectively connected as will appear, the aforementioned shifting structure for reversing the motor. The tubes are penetrated by a rod 22 having end heads 22a between each of which and casting 21 is a spring 23. Such rod and the springs form back-and-forth movable means to impose spring pressure on said structure, and if the latter is held by the corresponding detent or pawl 19 against such movement power to move said stiuctiu'e in such direction will be stored up in the interposed spring, and if then the detent is retracted said structure will be shifted by the spring in said direction. It is not essential that this means to impose spring pressure on said structure in this way be actuated automatically but I prefer so to actuate it thus, for instance as follows (see Figs. 4 and 6 to 9).

The casting 21 is hollowed out underneath (Fig. 8) and at that point the rod 22 has a pitman 24 pivotally connecting it with a crank 25 freely revoluble on one of the shafts l3 and having its hub (to which the lead-line for character 25 actually extends in Figs. 6 and 8) laterally prolonged (as seen by a comparison of Figs. 6 and 8) and formed with a top web 26 affording two opposite side faces 26a (Fig. 4) either of which may abut a wall 27a as the crank is turned one way or the other to thus limit its rotation to 180; said wall 27a is simply an upstanding flange (see Figs. 2, 4 and 6) at the back of an upwardly bulged portion of a cover plate 27 which is otherwise generally inclined forwardly and downwardly (Figs. 2 and 5) and is secured to the frame at 28 (Fig. 5), and whereas the web of the crank is arranged to impinge against wall 27a, as stated, the arm 25b of the crank, to which pitman 24 is connected, is below this wall, that movable underneath the bulge as shown by dotted lines in Fig. 2 and also compare Fig. 6. Plate 27 has a rearwardly extending slot 27m (Fig. 4) to admit the crank when the plate is placed in position. Fast on the lower end of said shaft is a collar 29 having one or more radial top cam-notches 29a adapted to receive a pawl 30 which is spring-pressed downwardly and contained in the crank, 31 being the spring also contained therein. The lower bearing 32 for this shaft (contained in the corresponding or left hand housing 13a Figs. 2 and 8) is formed with a partcircular depending segmental projection 33 at the back thereof and of suchcircumferential extent that when the crank is moving from one of its mentioned limits to the other said projection will overlie the pawl 30", so that the latter is prevented from rising. Assume that the shaft, rotating in synchrony with the corresponding beam, is turning in the direction of the arrow in Fig. 6, the crank being at one of its limits against the wall 27a as shown in Fig. 4 and the pawl clicking idly over the notched top of collar 29, and next assume that the shaft starts to re-rotate; the pawl, falling into the first notch to approach, will pass under the projection, which will lock the pawl in the notch and thus the crank to the shaft, so that it re-rotates therewith. This latter will continue until the pawl clears the projection at its opposite side-the crank also reaching its other limit-, whereupon the shaft will continue rotating pitman and crank becomes effective to store up tension in one or the other spring.

Assume that the piece is passing toward the left in 2 and that the right-hand detent or pawl 19 is holding the mentioned structure (including the slide and switch) in the left-hand position so that the motor is driving the beams in the direction appropriate to such pass, the described means to impose spring pressure acting on said structure toward the right. When the lot piece has nearly unwound from the right-hand.

beam and consequently the adjoining controller l5-16 depresses said detent or pawl 19 said structure will be released and reverse the motor. Shafts 13 now starting to re-rotate the left-hand beam in the way described will cause the crank to reverse its positionor take the position of Fig. 2-which will mean that said means will now exert spring pressure on said structure toward the left, and since the left-hand detent is now free of its controller l516 it opposes movement of.

said structure so that the spring power becomes stored up for shifting of said structure to the left when the latter is next released by the lefthand detent. In short, when a pass in either direction is about finished release of said structure under tension of one spring is effected from fthe train of parts l0-2--13-15 including the then delivering beam and when as a consequence reversal of the motor and two beams occurs and the pass in the opposite direction has begun the other spring is tensioned so as to be prepared to shift said structure when that pass is about finished. In this way the machine might continue to reverse itself indefinitely.

(While the machine as herein shown and described in detail is adapted to reverse and, as it 1 were, re-reverse, and so on, alternately, I do not wish to exclude a single reversing action.)

However the machine may be stopped at any time manually, as by disconnectively coupling the controller 6 with the slide so that the former may be manually moved to the off position to stop the motor-that is, its mid-position. For this purpose let 34 be a control rod which is connected with the controller 6 by the gimbal joint 35 and may slide in brackets 18 lengthwise and also rock therein and in the joint the same having two end handles Bea which by their weight hold a middle handle 34?) with a roller 36 thereon normally engaged in a slot 21a of the slide. If this control rod be depressed to clear the roller from said slot the slide and hence the controller can be shifted, independently of the slide, to the off position to stop the machine.

It is desired to stop the machine automatically when some predetermined mimber (one or more) of passes have been effected, for which purpose when the last shift of the mentioned shifting or motor-reversing structure occurs it should be stopped part way or" its normal stroke, so as to leave the controller 6 at the off position. Hence a revoluble ratchet 37 i journaled in the coverplate 2'? and its journal stud 38 carries above the plate an elastic arm 39 equipped with a handle 40 and a pin ii held by the elasticity of the arm against the plate. in the circular path of the pin with the arm is a numbered series of recesses 42 in the plate all of which are mere rounded depressions with which the rounded end of the pin have slip engagement excepting that indicated 420;, which is a hole to receive the pin and form a positive stop for the ratchet. The casting 21 has two reversed pawls as spr1ngheld against stops 4.4. When said reversxig structure is at either limit one pawl is engaged with the ratchet and the other spaced thereirom distance corresponding to the spaces between the catching po ts formed at i2 and 42a (the normal range of movement of said structure being twice that distance), wherefore the first half of the stroke of said structure in either direction to turn the ratchet is abortive. The ratchet is set with the arm at the catching point i, for example. When it is shifted on the completion or" the next to the last pass it will be positively stopped at 42c and the then working pawl on the last pass will therefore come against the now checked ratchet, stopping the slide at the midpoint in its normal stroke. In other words, given the reversing structure movable to a definite position to reverse the motor and then back, and so on repeatedly, there is means, on one of the strokes of said structure toward said position, to check the same short of said position comprising a ratchet arranged to be normally rotatedthrough a definite range by said structure, the fixed structure of the machine having a stop to check the ratchet and hence the reversing structure on said stroke or" the latter; in the example, where the reversing structure is movable to either of two positions in each of which it reverses the motor, said means is adapted to operate to check said structure short of either position, according to which of them it would otherwise approach.
